Motherwell midfielder Steve Jennings has denied any wrongdoing as investigations continue into betting patterns surrounding his red card against Hearts.
The Association of British Bookmakers reported unusual bets being placed on the prospect of a sending-off in Tuesday's Clydesdale Bank Premier League game. The ABB reported their findings to the Scottish Football Association and the Gambling Commission.
It is unclear how many bets were placed but the ABB said on Thursday that two of their members had sparked the alert, including Blue Square. Blue Square later revealed that only one customer had aroused their suspicion.
Spokesman Alan Alger told BBC Scotland: "At 2pm on the day of the game we had a new account opened that was planning to back a red card for Motherwell at 10-1.
"That new account tried to place as much as the account would allow but we`ve got certain measures in place that stop duplicate bets and bets of a certain amount on certain markets.
"That person did return and tried to then place another £100 at 10-1 and consistently in the lead-up to kick-off tried to get as much money as possible through that account on that particular bet, but those fail-safes at our end stopped that.
"The customer stood to win £2,000 from a Motherwell red card. We`re withholding that pending investigation."
Jennings has been told not to speak publicly by his employers but he is understood to have categorically denied any wrongdoing.
The 26-year-old, who had been booked for a foul in the early stages, received a straight red in the 83rd minute for showing dissent to Stevie O`Reilly, who has now sent off 11 players in 16 games this season.
Motherwell caretaker manager Gordon Young on Thursday dismissed any suggestions of impropriety on his player's part, saying: "I believe it will be unfounded. The first and foremost thing is for the player to be exonerated because it has no bearing on the individual. Everyone at the club is 100% behind him."
